Multiroute yield experiments were carried out on extruded ZK60 magnesium alloy samples under 200 °C and strain rate of 10−2 s−1 by a thermomechanical simulator. A hypoelastoplastic large deformation constitutive relationship was employed to simulate subjected uniaxial loading, biaxial loading-reverse orthogonal loading in the finite element (FE) software with user subroutine. The results showed...
